TO ALL WHOM IL MAY CONCERN; l

Be it lrnown that'I, MILTON NBLES, of Elmira, in the connty of Chenin-ng, and State ot' New York, have invented certain new and useful improvements in Boat-Dataching:Apparatus; Aand I do hereby declare the 'fols lowing tombe a full, clear,'and exact dscriptienjof the same, reference being hadto the accompanying drawings, making a part of this specieation, in `which Figure 1 represents a tcpplan of a life orother' boat, with the disconnecting apparatus in place. 'Figure 2 represents a vertical longitudinal section'through .the boat, and showing a side elevation oi' the disconnecting'apparatus.'

Figure 3 represents oneof the tripping-rods'for operating the letego. y

Similarletters'of reference where they occur in the vseparate'guresdenote like lparts in allthe drawings.

The object and purpose of this invention are-to avail myself 'of the central detaching devices, whilst I also steady the boat laterally'r andv prevent it from tipping when hastily let go or unevcnly loaded; and my invent-ion consists in centrally suspending` the boat, -but bracing it laterally to prevent tipping or rocking by uneven loading, and in either leaving the brace'with thcbolt or letting it go with the davit-blocks or otherlowcringr tackle.'l

To enable others skilled in the art to make and use my invention, I will proceed to 'describe the same with reference to the drawings. l Y

On the-right of fig. 1 I have represented a bar. or brace a, which, when the boat is disconnected from the lowering tackle, goesl with the tackle. This bar lies between studs or pins 1 2 4and 3-4, arranged on the sides of the boat, and from each of its ends and from its centre metal rods or straps I1 extend town-rd cach other, and termi-nate in an eye, c,int'o which the lowering tackle is hitched. From the centre of this bar' a a'suspensionrod, talig. 3, extends downward into'atube, @,aud is gnided and.A held therein by the enlarged portionfinto a hole'in which the rod glshoots after passingthrougl. the tube. The pins in this case lreep the bar in pla-ce, and the bar serves to prevent'thc boat fromA tipping; but when the rod-or bolt g isiwithdrawn from'the hole in the piecef, -then the whole brace is disconnected fr omvtl'ie 'boat and goes with the lowering tackle..v

On lthe fright of g'. 1' I have shown a inodieatienef that just above described, whereinthe brace is hinged `to the boat at z', and has a central suspension-rod, d', that moves through a collar or ring, vz, onthe brace; and lto the top of this rod is hinged a hook or bent lever, 1t, the point of which catches and holds iu theV ring or collar la, but when the rod or bolt g is withdrawn thcsusponsion-rod has no rigid .connection with `the boat, the latter drops and its rst movement slips the ring or collar L fronithe point of the hook, which allows it to fly anddetach from the lowering, tackle. The two rods or bolts-g g may be simultaneously withdrawn by the pivoted lever m, to which theyl are connected zit-uniform distances each side f'its point of vibration, and may be 'as and for the purpose herein described and represented.

moved in contact vwith rollers 'to remove friction caused by the weight upon them.

Having thus fully described i'ny'inventien, what I claim therein as new, and desire to. secure by Letters Patent, is

The combination of the ldetaching apparatus with the brace, and with. the central suspension of the boat,
